This invention relates to a bracelet strap more particularly designedfor securing a wrist watch on the arm of the wearer; and has for itsobject to securely fasten cross which have their extremities foided overthe edges of the strap to finish the same, to the strap so that the barswill not become loosened and detached from the strap while in use.

A further object of the invention is the provision of projections on thecross bars to extend into the strap to prevent the cross bars fromsliding on the strap or becoming detached from the strap when the sameis purposes.

iVith these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully de scribed, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a top plan View of a strap indicated as being formed of meshwith the cross bars secured thereto their extremities being folded overthe edges of the strap and visible from its opposite side to form abordering margin therefor.

Figure 2 is a bottom view of the strap with cross bars mounted thereon.

Figure 3 is a perspective view of one of the cross bars with my improvedspurs shown on its edges.

Figure 4 is a side elevation showing the spurs as formed at a differentlocation.

Figure 5 is a side elevation showing the spurs as located at both thebottom and ad jacent the extremities of the cross bar.

Figure 6 is a section on line 66 of Figure 2 showing the projection bentinwardly from the cross bar forming a recess in the bottom thereof.

Figure 7 is a sectional view on line 7-7 of Figure 2 showing the strapas engaged by the projections as illustrated in Figure 4.

Figure 8 is a view similar to Figure 7 showing both projections in theirrelative positions to the strap.

A strap of the character herein described formed of mesh with its edgesbound by the folded edges of cross bars is used extensively for securingwrist watches to the arm of the wearer, with which straps it iscustomary to associate an extension device which may have foldingsections and to which it is desired to adjustably detach an end of thewrist watch strap. Eccentric clamps are provided for gripping the strapand securing it to the extension device, the size adjustment being madeby cutting off the strap with a pair of scissors or the like to-thecorrect length be fore it is clamped into the extension device but it isfound that in making a bracelet strap shorter by cutting off its endsthat the cross bars are often detached from the strap either by slidingfrom the severed end or by the parts being bent to permit suchdetachment and in order to avoid this undesirable result, I haveprovided means additional to the folding of the extremities of the barover the side edges of the strap to hold the cross bar in place thereon,consisting of projections to be forced onto the mesh for this purposeand the following is a detailed description of the present embodiment ofthis invention illustrating the preferred means by which theseadvantageous results may 'be accomplished "With reference to thedrawings, 10 designates a bracelet strap which may be made of anysuitable material but is here illustrated as being formed of mesh fabriccomposed of intermeshing strands of wire. Cross bars 11 extend withtheir extremities 12 folded over the side edges 13 of the strap and inclose contact with each other to bind the rough edges of the strap andform borders 14 for the top of the strap as is clearly illustrated inFigure 1. The portions 15 of the bars intermediate the edges of thestrap are formed narrower than their side portions to leave a space 16between them in order to permit of greater flexibility of the strap.

Spurs 17 are provided on the edges of the cross bar as illustrated inFigure 8 and spurs 18 may be provided on the side or folded portionsadjacent the extremities of the cross bars to penetrate the strap whenthe cross bars are positioned thereon as indicated in Figures 7 and 8 tolock the bar in place and as an additional optional means of securingthe cross bar to the strap, I may strike the cross bar on the back ofthe strap with a tool similar to a prick punch to provide projections 0rdetent 18 at either side thereof forming a recess 20 in the bar whichfurther assists in binding the strap between its back portion and thefolded side portions or extremities, as illustrated in Figure 6.

By the provision of the above means which are additional to the foldingof the extremities of the bars over the edges of the strap for securingthe same thereto I provide a means whereby the bars cannot slide alongthe strap or become detached therefrom upon severing the strap foradjustment purposes and which secure the cross bar in place even thoughthe strap with its cross bars are twisted or bent due to injury or roughhandling.

The foregoing description is directed sole- 1 towards the constructionillustrated, but

desire it to be understood that I reserve the privilege of resorting toall the mechanical c ianges to which the device is susceptible, theinvention being defined and limited only by the terms of the appendedclaims.

I claim:

1. A bracelet strap comprising a body formed of intermeshing strands ofwire, cross bars on the back of said body extending laterally thereofwith their extremities in close adjacency and folded over the edges ofthe body to form a border for the front of the strap, the portion ofsaid bars intermediate the extremities being narrow to permit offlexibility, and pro ections on said cross bars and also intermediatetheir peripherial edges and adjacent the side edges of said body toextend into said body and prevent sliding and detachment of said barsfrom said body.

2. A bracelet strap comprising a body formed of intermeshing strands ofwire, cross bars on the back of said body extending laterall thereofwith their extremities in close ac acency and folded over the edges ofthe body to form a border for the front of the strap, the portion ofsaid bars intermediate the extremities being narrow to permit offlexibility, and projections on said cross bars to extend into said bodyand prevent sliding and detachment of said bars from said body.

In testimony whereof I affix my si nature.
